Information

The Copeland D3DC piston ring is a cylindrical pin installed on the piston skirt. Its middle part passes through the small head hole of the connecting rod, and then it is mainly used to connect the piston and the connecting rod. And it is more common in our lives. The following editor will introduce the main function of this Copeland D3DC piston ring, right? If you are also interested, you might as well take a look. Hope to help you all.

Copeland D3DC piston

   Copeland D3DC piston ring has many types, and the types used in different places are still different, but the effect is the same. Its function is to transmit the aerodynamic force that the piston bears to the connecting rod, or to make the small head of the connecting rod drive the piston to move together. And when it is used, it is mainly to reduce weight. Piston pins are usually made of high-quality alloy steel and made hollow. In addition, we also need to know that this Copeland D3DC piston ring is also mainly used to connect the piston and the connecting rod. At this time, it transmits the force of the piston to the connecting rod, and vice versa. Copeland D3DC piston ring bears great periodic impact load at high temperature. This is because the piston pin swings at a small angle in the pin hole, which makes it difficult to form a lubricating oil film, and its lubrication conditions are poor at this time. Therefore, the Copeland D3DC piston ring must have sufficient rigidity, strength and wear resistance, and the mass should be as small as possible. Moreover, its pins and pin holes should have a proper fit clearance and good surface quality. Therefore, the stiffness of the Copeland D3DC piston ring is generally very important. If the piston pin is bent and deformed, it may damage the piston pin seat.

   These are some basic information related to the Copeland D3DC piston ring. You should pay more attention to it in normal times. In short, the working conditions of Copeland D3DC piston ring are high pressure ratio, no oil film can be formed, and deformation is not coordinated. Therefore, its design requires high mechanical strength and wear resistance, as well as high fatigue strength. In addition, we also need to tell everyone about the material of this Copeland D3DC piston ring. The material of Copeland D3DC piston ring is generally low-carbon steel or low-carbon alloy steel. Low-load engines often use 15, 20, 15Cr, 20Cr, 20Mn2 steel, and when it strengthens the engine, then CrNi3A, 18CrMnTi2, 20SiMnVB will be used at this time And other high-grade alloy steel, sometimes 45 medium carbon steel can also be used. But in order to make the outer layer hard and wear-resistant, it is necessary to heat the Copeland D3DC piston ring. In addition, the outer surface of the low carbon steel piston pin needs to be carburized and quenched. At this time, you mainly follow the Copeland D3DC piston ring. The size of the ring and the depth of its carburized layer are generally in the range of 0.5-2mm. The surface of the 45 steel piston pin is quenched, and the depth of its quenched layer is 1-1.5mm. It should be noted here that Copeland needs to be quenched. The D3DC piston ring cannot be completely hardened, otherwise it will become brittle.
